JOHN M. FARRIER, OF DAYTON, OHIO, ASSIGNOR OF ONE-HALF OF HIS RIGHT TO MORRIS KASMIRSKY, OF SAME PLAGE.

WINDOW-BLIND.

SPECIFICATION forming part of Letters Patent No. 225,117, dated March 2, 1880.

Y Application filed November 28, 1879.

vuseful Improvementsin Window-Blinds; and

I do hereby declare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this speci iication.

Figure l is a plan view. Fig. 2 is a side view. Fig. 3 is an end view, and Fig. 4L is a sectional View on the line y y, Fig. 5. Fig. 5 is a sectional view on line :o w, Fig. 4.

Corresponding parts in the several figures are denoted by like letters of reference.

This invention relates to blinds for the windows of buildings, railroad-cars, and other places; and it consists in certain improvements in the construction of the same, will be hereinafter fully described, and particularly pointed out in the claim.

My improved window-blind is made up of a series of separate slats, A A, strung upon and connected by wires B B. The slats Aconsist of wooden strips of suitable dimensions, the upper and lower sides of which are beveled in opposite directions, as represented at O O', Figs. l and 5. The lower edge of each slat is provided with a triangular projection, D, tting into corresponding V-shaped notches E in the upper edges of the slats below.

The slats are provided with vertical perforations to receive the connecting-.wires B. Loops F, formed at the upper ends of the latter, enter corresponding recesses F in the upper slat, A', thus preventing the connectingwires from turning when the nuts G are ad- 4o justed upon the lower screw-threaded ends of said connecting-wires.

In operation, a suitable number of slats to form a blind of the desired size are connected by the rods or wires B B.

Suitable top and bottom pieces may be substituted for the upper and lower slats, and the bindingnuts may be secured by screws, as represented in the drawings.

The binding-nuts, it will be observed, oper- 5o ate to tighten the slats upon the 'connectingrods, so as to form a non-exible blind.

Having thus described myinvention, I claim and desire to secure byLetters Patent of the United States- A shutter or blind composed of slats fitted which to each other with a joint V-shaped in crosssection, and united by wires threaded through the same andtightened by a nut or other suitable means, whereby a non-flexible blind is formed and the slats are kept in line with each other, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

JOHN M. FARRIER.
